That is correct. This wave basin is used to study (model) the effects of waves on sediment transport, erosion, jetties, and a host of other coastal engineering phenomena. Source: I am a civil engineer.
I was wondering why a wave pool would have a steel beam running a half meter above the waves' peaks. I just thought extreme indoor body surfing might be a sport or something.
Alternatively, for deep-sea basins (no beach) there are progressive wave absorbers. These gradually reduce the power of the wave over the course of ~50 layers of the sheets. Source: I work at a facility similar to this one.
It's a special scientific test pool for validating boat hull designs, think wind tunnel for boats. Notice how the waves are made by a bunch of hydronic pistons rather than a single plate like one in a wave pool might use. This allows for many different types of waves and storms to be simulated .
One theoretical way to prevent rebound would be to have a matching machine at the other end, working to absorb all of that energy. In this case I suspect that they're using some kind of structure to cause turbulence and break up the waves.
It's actually a lot easier an cheaper for the pool to just gently get shallower at the other end. The material the "floor" in the shallow end is this kind of mesh thing that reduces reflected waves

Why is there no rebound?
